Abstract
The utility model provides a polyethylene enwound walled pipe with metal reinforcing ribs, which is produced by spiral winding of polyethylene hose and welding with hot melt adhesive. In the process of spiral winding and welding with hot melt adhesive, at least one metal reinforcing rib is wound simultaneously. The metal reinforcing ribs and the hot melt adhesive are both adhered between two adjacent wound pipes and are arranged at the exterior wall of the wound pipes. Because at least one metal belt or metal strip is wound simultaneously in the process of spiral winding and welding with hot melt adhesive, the entire enwound walled pipe is embedded with a metal belt or metal strip to form a spring-shaped structure, which enhances the ring stiffness of the enwound walled pipe and is advantageous to reducing problems of cold shrinkage of plastic pipes due to higher creep ratio via the tension of springs.
Description
Technical field
The utility model relates to a kind of plastic tube, relates in particular to a kind of polyethylene spirally enwound structure-wall tubular product with metal reinforcing.
Background technique
The polyethylene spirally enwound structure-wall tubular product purposes is boundless, and its main advantage can use mini-plant to produce the tubing of bore greater than 1000mm aspect bore.But because the raw material that polyethylene spirally enwound structure-wall tubular product uses mainly is a polyethylene, and polyethylene self Young's modulus is less, and the ring stiffness of the tubing of making can't meet the demands, so limited the application and the development space of polyethylene spirally enwound structure-wall tubular product.
In order to increase the ring stiffness of entwining tube, the at present use at entwining tube outer surface increase steel band, steel rib etc. strengthens structures more, though its product has increased the ring stiffness of tubing, but owing to structural reason, make the product structure instability, force bearing point is too concentrated, thereby make structure destroy extremely easily, and steel band, steel rib combine too much with the plastics outer surface, makes the binding site peeling force very low, existingly moulds junction plane because of destructurized and steel and peel off the engineering accident that causes.
The model utility content
The purpose of this utility model is exactly in order to solve the problem that above-mentioned prior art exists, a kind of polyethylene spirally enwound structure-wall tubular product with metal reinforcing to be provided.
In order to achieve the above object, the utility model has adopted following technological scheme: a kind of polyethylene spirally enwound structure-wall tubular product with metal reinforcing, be welded through the spiral winding and with hot melt adhesive by vinyl tube, be characterized in, in the spiral winding and in the hot melt adhesive welding, be wound with at least one metal reinforcing synchronously, this metal reinforcing is bonded between the two adjacent entwining tube with hot melt adhesive and is positioned at the outer wall side of entwining tube.
Described metal reinforcing is 3～10mm apart from the distance of entwining tube outer wall.
The width of described metal reinforcing is 10%～90% of a hot melt adhesive weld width.
Described metal reinforcing is metal tape or metal bar.
Described vinyl tube is the hollow, rectangular plastic tube.
The utility model makes it compared with prior art owing to adopted above technological scheme, has following advantage and characteristics:
1, can improve the tubing ring stiffness under the equal conditions.
2, can reduce the raw material use amount, save resource.
3, metal tape in the metal reinforced plastic hot melt adhesive or metal bar form spring type in the pipe structure wall, and the tension force by spring self has reduced plastic tube because the cold and hot contraction problem that self creep ratio causes more greatly.
Description of drawings

The structural pipe wall enlarged view of the polyethylene spirally enwound structure-wall tubular product of Fig. 2 the utility model band metal reinforcing.
Embodiment
Referring to Fig. 1, Fig. 2, the polyethylene spirally enwound structure-wall tubular product of the utility model band metal reinforcing, be welded through the spiral winding and with hot melt adhesive 2 by vinyl tube 1, in the spiral winding and in the hot melt adhesive welding, be wound with at least one metal reinforcing 3 synchronously, this metal reinforcing 3 is bonded between the two adjacent entwining tube with hot melt adhesive and is positioned at the outer wall side of entwining tube, and its distance apart from the entwining tube outer wall is 3～10mm; Its width is 10%～90% of a hot melt adhesive weld width.Metal reinforcing 3 wherein can be metal tape or metal bar.Vinyl tube 1 wherein is the hollow, rectangular plastic tube.
The manufacture process of the polyethylene spirally enwound structure-wall tubular product of the utility model band metal reinforcing is: be raw material with the polyethylene, extruding hollow, rectangular plastic tube material embryo by extruder, is the hollow, rectangular plastic tube with hollow, rectangular plastic tube material embryo by vacuum battlements formula cooling unit cooling and shaping.Also emit metal tape or metal bar synchronously by extruder extrusion plastic hot melt adhesive, make hot melt adhesive be coated on metal tape or metal bar outside formation metal reinforced plastic hot melt adhesive.At last step hollow, rectangular plastic tube and metal reinforced plastic hot melt adhesive are made the polyethylene spirally enwound structure-wall tubular product of being with metal reinforcing by steps such as winding, cooling, pressings.
The polyethylene spirally enwound structure-wall tubular product of this band metal reinforcing of the utility model is because in the spiral winding and in the hot melt adhesive welding, be wound with (or several) metal tape or metal bar synchronously and constitute metal reinforcing, make that having embedded one (or several) in whole winding structure wall pipe twines the spring shape structure that forms by metal tape or metal bar, help tension force by spring self and reduce the cold and hot contraction problem that plastic tube causes more greatly owing to self creep ratio.
